template: date filter improvments: new format (i.e. format after date limit has been reached) can now be specified. 0 can now be used for "auto_limit" to use last midnight as date limit. A new "auto_day" format can be used as shortcut to use last midnight as date limit, short datetime for old format, and time only for new format.
